A spokesman for Mendes declined to confirm the report but
did issue a statement saying the 33-year-old actress had taken
time off to "attend to some personal issues."

"Eva has been working hard for the past year and made a
positive decision to take some much-needed time off to
proactively attend to some personal issues that, while not
critical, she felt deserved some outside professional support,"
said the statement from spokesman Brad Cafarelli.

Celebrity Web site TMZ.com said Mendes had checked into the
Cirque Lodge rehab center in Utah, which is the same facility
in which actress Lindsay Lohan sought help late last year.

The news of Mendes' stint in rehab came on the same day
that Calvin Klein Inc. said Mendes would be featured in an
upcoming advertising campaign for Calvin Klein Fragrances.

"We support Eva during this difficult time and respect her
decision to seek professional help," Calvin Klein Inc. said in
a statement.

The actress starred in four movies in 2007 including the
thriller "Ghost Rider" and the cop drama "We Own the Night."
She has two films planned for this year, "The Women" and "The
Spirit."
